This is my PB, but it could have been faster. I forgot an edge pair in cube 4 I had to go back and fix. I also took a while recalling corner memo on cube 5, but once I remembered, I went balls out to finish.

First solve done BLD: [35:26.78, 20:46, 2C].
I twisted two corners the wrong direction. On this solve, I popped an edge, and I got lucky and put it back in correctly, and I also got confused a couple of times, yet I almost got it right!

First solve done BLD: [13:27.83, 9:57, case DB, 4C 4E].
I really need to spend some time practicing square-1 BLD; I've gotten really bad at it. First I had trouble recalling the matrix, then I miscalculated the piece to start lettering on when translating, and memorized most of the edges before I realized what I had done. I eventually managed to get the memorization right, though, but then I forgot whether or not I had done a setup move when preparing to do an algorithm, so I did it again. :(
